Sep 13, 2015 · This is the same question my teacher asked 4 years ago so I know the answer is still the same. Here if what I turned in to my teacher. "The Philippines is very lucky & unique because it has almost every known metal in the world loed here.
THE EXTRACTION OF METALS AN INTRODUCTION. This page looks at the various factors which influence the choice of method for extracting metals from their ores, including reduction by carbon, reduction by a reactive metal (like sodium or magnesium), and by electrolysis.
The process of procuring metals from ores is called metallurgy and these naturally occurring compounds of metals are known as minerals. Metals are usually extracted from the earth by mining. Ores. All ores are minerals, but not all minerals are ores. Ores are those minerals which contain metals. The picture shown above is a goldbearing ore.

How are metals extracted from mineral ores? How do we make iron, steel, other alloys, aluminium, sodium, copper, zinc, titanium and chromium. The six linked pages include an introduction to metal extraction or metal manufacture and production. There are detailed notes on the extraction of iron and its conversion to steel. The extraction and manufacture of aluminium and sodium are described.
An ore is any naturallyoccurring source of a metal that you can economically extract the metal from. Aluminum, for example, is the most common metal in the Earth''s crust, occurring in all sorts of minerals. However, it isn''t economically worthwhile to extract it from most of these minerals.
Sep 03, 2014 · ore metal compound separated from bits of sand & rocks purified metal compound metal extracted metal chemically separated from other elements 8. The Extraction of Metals •The lower the position of a metal in the reactivity series, the easier it is to extract. The reactivity series and the method of extracting metals 9.
Home → 50.5 EXTRACTION OF METALS METALLURGY . The process of extracting pure metal from its ore is known as metallurgy. . Since, the nature of the ore and also the properties of different metals are different, therefore, it is not possible to have the universal scheme which may be applicable to all the metals.
Metals are extracted from ores. An ore is a rock that contains enough of a mineral (metal compound) for the metal to be extracted from it. Most metals are extracted from an ore by reduction with
18.2. General Principles of Extraction of Metals The process of extracting the metals from their ores and refining them is calledmetallurgy. The choice of the process depends upon the nature of the ore and the type of the metal. The metal content in the ore can vary depending upon the impurities present and chemical composition of the ore.
Metal ore is a type of rock from which metal can be extracted. Metal ores are normally oxides for example, aluminum is the most common metal in the Earth''s crust, but in order to get as pure
It is more expensive and wasteful to extract a metal from a low grade ore, but most high grade ores have already been used. Extraction methods. The extraction method used depends on the metal''s
Vanadium processing, preparation of the metal for use in various products. Since the early 1900s, vanadium has been used as an alloying element for steels and iron. In 1905 Antenor Riza Patron discovered a large asphaltite deposit containing rich vanadium ores in Mina Ragra, Peru. Two years later
The exploitation of metal ores to extract metals causes pollution and uses up the Earth''s limited resources Metals are more expensive than other materials such as concrete. Chemistry: metals 45 terms. maevepreston. AQA GCSE Core Chemistry Revision (C1) 55 terms. greenie31478.
1. Introduction to the extraction of metals. What methods can be used in extracting metals from mineral ores? The Earth''s crust contains many different rocks.. Rocks are a mixture of minerals and from some we can make useful substances.. A mineral can be a solid metallic or non–metallic element or a compound found naturally in the Earth''s crust.
How Are Metals Extracted From Their Ores? Metal extraction from ores occurs in many different ways involving physical, chemical and electrical means. Even ores of the same metal sometimes require different methods of separation depending on the concentration of the metal and its chemical composition within the ore.

Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied. The field is a materials science, covering all aspects of the types of ore, washing, concentration, separation, chemical processes and extraction of pure metal and their alloying to suit various appliions, sometimes for direct
Extracting of Copper from Other Ores. Copper can be extracted from nonsulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solution.
Dec 21, 2016 · A list of important metals with ores is given in this article which will give an idea of metals and from where they are extracted. It will help in
The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfurbearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

Extracting iron from iron ore using a Blast Furnace. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source.
The reactivity series shows metals in order of reactivity. The reactivity of a metal is related to its tendency to form positive ions. Iron and aluminium are extracted from their ores in various ways.
Ores And Minerals – Isolation of elements in Chemistry class 12 th aims to teach the students about the various processes of extraction of metals from ores. Very few metals such as the noble metals, i.e., Gold, Silver, Platinum, etc are present in their original metallic forms in nature.
